Solve the system using substitution <br> y=8-x <br> 7=2-y

Alexus [3.1K]

If y=8-x then you can plug that into the equation like 7=2-(8-x). When you distribute the equation becomes 7=2-8+x. Once you combine like terms the equation becomes 7=-6+x. Then you subtract 6 from both sides, which gives you 13=x.
To find y just put 13 where x was in the first equation. Y=8-13.
Y=-5
X=13

sammy [17]

Answer:

The amount of interest is $5580.

Step-by-step explanation:

Given : Jacob borrowed $30, 000 to start up his consulting business. The loan had simple interest rate of 6.2% for 3 years.

To find : The amount of interest he will pay with the loan ?

Solution :

Using interest formula,

$I=P\times R\times T$

Where, P is the principal P=$30,000

R is the rate of interest R=6.2%=0.062

T is the time t=3 years.

Substitute the value in the formula,

$I=30000\times 0.062\times 3$

$I=5580$

Therefore, The amount of interest is $5580.

I. The Bread Machine (25 points)

Naddika [18.5K]

It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Let x represent the rate of cost of one loaf and y represent the total cost, hence:

y = 0.8x + 100

The rate of cost of one loaf is $0.8 and the start up cost is $100.

For the second bread it is given by:

y = 1.6x

The graph of the two equations cross at (125, 200)

It would take 125 loaves at a cost of $200 for the breadmaker and store bought bread to cost the same.
